Radio giant pulses provide a unique opportunity to study the pulsar radio emission mechanism in exquisite detail. Previous studies have revealed a wide range of properties and phenomena, including extraordinarily high brightness temperatures, sub‐nanosecond emission features, and banded dynamic spectra. New measurements of giant pulse characteristics can help guide and test theoretical emission models. To this end, an extensive observation campaign has begun which will provide more than 500 hours on the Crab with a 34‐meter antenna located in California, USA. The observations are being done as part of an educational outreach program called the Goldstone‐Apple Valley Radio Telescope (GAVRT). This antenna has a novel wide bandwidth receiver which provides up to 8 GHz of instantaneous bandwidth in the range of 2.5 to 14 GHz. These observations will provide detailed information about the variability, amplitude distribution, and detailed frequency structure of radio giant pulses. In addition, a database of pulses from these observations and others of the Crab pulsar is being created which will simplify multiwavelength correlation analysis.

Additional Information:© 2011 American Institute of Physics. Published online 18 August 2011. Ryan Shannon and Jim Cordes are co-investigators on the GAVRT/Fermi gamma-ray/radio correlation study which is partially supported by NASA through a grant from the Fermi Space Telescope guest observer program. These observations would not be possible without the excellent work by the entire DSS-28 implementation team at Caltech, JPL, and the Lewis Center. The digital signal processor was made possible by generous hardware and software donations from Xilinx, Inc. The author is supported by a Jansky Fellowship from the National Radio Astronomy Observatory which is operated by cooperative agreement between the National Science Foundation and Associated Universities Incorporated.
